Flip flop dates back more than 5000 years to the Egyptians and was considered the footwear of royalty. Different styles were even used to distinguish social classes. The rulers wore flip flops that curved up on the sides.
The Germans were the first to manufacture the slippers in modern times. The name that was synonymous with flip flop originally was 'thong' as the German's actually trademarked the name flip flop.
Flip flop consists of a flat rubber sole and a thong strap that holds the sole to the foot. The strap is a simple Y-shape that allows the big toe and the second toe to grasp it, keeping the rubber sole close to the front of the foot. The name likely came from the floppy sound that the rubber sole makes when you walk in them. As the back of the sole hits the foot, you can hear a distinct popping sound.
